Ariel Castro confirmed as father of 6-year-old in Cleveland kidnapping case

(USA TODAY) -- During interrogation with police, Ariel Castro, the man charged with kidnapping and raping three women over roughly 10 years, referred to himself as "cold-blooded," addicted to sex and unable to his impulses WKYC Channel 3 News has learned.

With exacting detail, Castro recalled the abductions of Michelle Knight, Amanda Berry and Gina DeJesus, explaining how he met each victim and even what he was wearing that day, according to sources.

Berry, 27, and DeJesus, 23, were abducted in separate incidents almost a decade ago. Michelle Knight was 22 when she was snatched from the streets in 2002.

Ohio Attorney General Mike DeWine's office said Friday that paternity tests showed that he is the after of Berry's 6-year-old girl who was also freed on Monday.

The 52-year-old unemployed school bus driver was "cocky" during the interview, showing remorse only over his capture, Channel 3 News was told.

Castro, who was arrested on Monday after Berry escaped from Castro's house with the help of neighbors and called police, was ordered held on $8 million bond Thursday by a Cleveland Municipal Court judge.

Meanwhile, in a suicide note discovered in his house by police, Castro blamed the girls for their abductions, writing that they were the ones who got into his car in the first place, the sources said. Castro did write that he wanted to give his money and possessions to the women if he was caught, the sources said.

The note appears to have written in 2004, about the time police were investigating him on an apparently unrelated matter involving a child left on his school bus. In the note ,he also mentioned his sex addiction, as well as having previously endured physical abuse as a child.

None of the abductions seemed planned, the sources said. Rather, they appeared to be crimes of opportunity.

Castro believed he would eventually be caught because he did not have "an exit plan" on how to deal with the three women and the girl he held captive in his Seymour Avenue home, the sources said. He just did not think it would be so soon.

In fact, Castro told police they had a chance to arrest him at one point but missed him, the sources said. It is unclear when that occurred.

In 2004, Cleveland Police knocked on Castro's door to investigate the case involving his school bus. A year later, a Cuyahoga County Sheriff's Deputy went to the home three times in an attempt to deliver a court summons.

Berry and DeJesus have returned home, while Knight remains hospitalized.
